Description

[Detailed explanation of the idea]

The present invention relates to a winding device, and in particular, an object of the present invention is to provide a winding device that can respond flexibly to various winding specifications. A conventional winding device has a configuration roughly shown in FIG. The winding mechanism consisting of the flyer 1 and the winding target object feeding mechanism consisting of the rotary table 2 are configured to be driven by the same motor 3.
A core 4 is the object to be wound, and is clamped by a core clamper 5 on the rotary table 2. Numerals 6 and 7 are clutches provided in the flyer drive system, which are switched so that when one is in the engaged state, the other is in the released state. Also,
Clutches 8 and 9 are provided in the rotary table drive system and are switched and set in the same manner as the clutches described above. The switching settings of the clutches 6 to 9 are performed in response to command signals from a control device 23, which will be described later. During winding operation, clutches 6 and 8 are first set in a coupled state. The rotation of the motor 3 is converted to a rotation suitable for winding work by a 1/ _N2 reduction gear 10, and is transmitted to the flyer 1 via a clutch 6.
This rotates around the core 4 in the direction of arrow A, and the guided wire 11 is wound around the core 4. On the other hand, the power driving fryer 1 is 1/
The rotary table 2 is decelerated by the _N3 reduction gear 12, rotates at low speed in the direction of arrow _B1 via the clutch 8, and sends the core 4. This feeding of the core 4 ensures the winding pitch. As the table 2 rotates, the rack 14 is linearly driven via the gear 13, and the rotation angle of the table 2 is converted into a linear movement distance of the protrusion 15. This protrusion 15 includes a pair of step disks 16a,
It moves between pin members 17a and 17b screwed onto pin 16b. First, a pair of disks 16a, 16
A plurality of pairs of pin members similar to the pin members 17a and 17b described above are attached to the pin member b in the circumferential direction. When the protrusion 15 moves and comes into contact with the pin member 17a,
This contact is detected by the sensor 22, and a detection signal is sent to the control device 23, which sends commands to each clutch. As a result, the clutches are switched, the clutches 6 and 8 are brought into the released state, and the other clutches 7 and 9 are brought into the connected state, and a return operation is performed to return the core 4 to the position at which it started winding the wire. The rotation of the motor 3 is reduced by a 1/ _N1 reduction gear 18 and transmitted to the flyer 1 via the clutch 7, and the flyer 1 rotates at a speed suitable for return operation. In addition, the power driving the fryer 1 is reduced by the necessary amount by a 1/N ₄ reduction gear 19,
The direction of rotation is reversed by the next stage gear 20 and transmitted to the table 2 via the clutch 9, and the table ₂ rotates at a relatively high speed in the direction of arrow B.
is returned to the winding start position. At the same time clutch 2
1 works and step disks 16a and 16b become 1.
The next pin member is selected by rotating by the number of steps. This return operation stops at the position where the protrusion 15 abuts the selected pin member 17b, the sensor 22 and the control device 23 operate, the clutch is switched, and the winding operation is performed again.
A second layer of windings is formed. The distribution state (pitch) of the windings formed by the above-mentioned winding operation is determined by the ratio of the relative rotational speeds of the fryer 1 and the table 2, and these are uniquely determined by the reduction gears 10 and 12. Note that the winding angle with respect to the core 4 is determined by the pin members 17a and 17b, and
A desired angle can be set by adjusting the screwing and fixing positions of a and 17b and arbitrarily setting the distance between them. In addition, the step disks 16a, 16
b is rotated to a predetermined position by controlling the clutch 21, and a pair of pin members facing the protrusion 15 is arbitrarily selected. The winding device having the above structure has various drawbacks as described below. The winding pitch is limited to a certain level, and it is not possible to respond to requests for winding with complicated specifications such as changing the winding pitch midway through. Since the winding pitch is set by the gear ratio, it is necessary to prepare many reduction gears with different gear ratios in advance. Setting the winding specifications requires skill and time. Also, sensor 2 due to backlash in the mechanism, etc.
The operating point in step 2 becomes unstable and the number of turns cannot be accurately controlled. Specifications cannot be set based on the number of turns, making inductance management difficult. It is mechanically complex, requires a high degree of skill for assembly and adjustment, is prone to failure, and is expensive. The present invention eliminates the above-mentioned drawbacks, and each embodiment thereof will be described below with reference to the drawings. FIG. 2 shows a schematic configuration of the first embodiment of the winding device according to the present invention. In the figure, the same components as those shown in FIG. . The winding device of this embodiment includes a microcomputer 30 as a control device, a control motor 31 as a dedicated drive source for the fryer 1, a pulse motor 32 as a dedicated drive source for the rotary table 2, and a control motor 31 as a dedicated drive source for the fryer 1. A proximity switch 33 is provided as a detector for detecting one rotation. The control motor 31 performs high-speed rotation, low-speed rotation, and stopping operations based on signals from the microcomputer 30. The pulse motor 32 rotates in the normal direction and
Performs reverse and stop operations. The microcomputer (control means) has two types of memory groups: a control program 34 and a winding data section 35. The control program 34 decodes the contents of the winding data section 35 and issues commands to the control motor 31 and pulse motor 32 according to the contents.
It also has functions such as decoding signals from the proximity switch 33. FIG. 3 shows an example of data for one winding forming the winding data section 35. The minimum unit of winding data is a pair of data A and data B. Data A and B each consist of 1 byte (8 bits),
It has a total of 2 bytes (16 bits). Therefore, N
Basically, to wind a turn coil, 2・N
Winding data constituted by bytes is stored in advance. Data A is the control motor 31 and pulse motor 3
Data B has a function of controlling the rotation, stop, etc. of the pulse motor 32, while data B has a function of representing the rotation angle of the pulse motor 32. Specifically, in data A, a ₁ and a ₀ indicate the rotational speed of the fryer 1, that is, the rotational speed of the control motor 31, as shown in Table 1.

[Table] a ₃ and a ₂ are pulse motor 3 as shown in Table 2.
2 instructs whether the proximity switch 33 operates regardless of the fryer pulse outputted when the rotation of the fryer 1 is detected or operates with reference to this fryer pulse.

[Table] a ₅ and a ₄ are pulse motor 32 as shown in Table 3.
Indicates the rotation status of.

[Table] When a ₆ is not used and a ₇ is 1'', it indicates the end of the winding work. In data B, b ₇ to b ₀ are pulse motor 32
Here, since the pulse motor 32 is configured to rotate by 1 degree with a group of 10 pulses, the above pulse number is a value 10 times the angle at which the pulse motor 32 should be driven, expressed in binary form. It can be said to give instructions in accordance with the law. Next, to explain the operation of the winding device having the above configuration, it is assumed that the microcomputer 30 reads out the following set of data from the winding data section 35. Data A (00010101) Data B (00001010) When these data are expressed in hexadecimal notation, data A
= 15, data B = 0A. The read data A and B are decoded by the control program 34. When the contents of this data are deciphered, it means that the fryer 1 rotates at a low speed and the pulse motor 32 rotates 1° in the positive direction in synchronization with the fryer pulse. Therefore, the microcomputer 30 that has decoded the above data (particularly a ₁ and a ₀ of data A) issues a low speed command to the control motor drive amplifier via the interface 36, thereby causing the control motor 31 to rotate at a low speed. Start. Rotation of the motor 31 rotates the flyer 1 fixed to this rotating shaft, and the wire 11 is wound around the core 4. Further, a shutter 38 having a fan-shaped projection on a part of the circumference of a disk is attached to the rotating shaft of the fryer 1. The shutter 38 rotates in a 1:1 relationship with the flyer 1, and when the flyer 1 passes outside the core 4, it passes close to the proximity switch 33.
(The detection section according to the present invention consists of a shutter 38 and a proximity switch 33.) When the shutter 38 passes, the proximity switch 33 emits a flyer pulse FP as shown in FIG. 4A. This flyer pulse FP is amplified by an amplifier 39 and is sent to the interface 3.
6 to the microcomputer 30. At this time, a ₃ and a ₂ of data A are 01, indicating the flyer pulse reference mode, so the flyer pulse FP is sent to the microcomputer 3.
Recognized by 0. microcomputer 30
Instructs the pulse motor 32 to rotate in the forward direction using data _a5 and _a4 of data A, and also a group of 10 pulses represented by data B (shown in FIG. 4B).
40. This pulse group 40 is applied to the pulse motor 32 via an interface 36 and a pulse motor drive amplifier 41, and the pulse motor 32 rotates 10 steps. This state is indicated by 42 in FIG. Here, gear 4 of the pulse motor 32
3 and the number of teeth of the gear 44 of the rotary table 2 is determined so that the table 2 rotates by 0.1° when one pulse is applied to the pulse motor 32. Therefore, when the fryer 1 rotates once, the table 2 moves in the direction of the arrow.
By rotating 1° in the _B1 direction, the wire 11 is wound around the moving core 4, and the core 4 is in the position where the next winding is to be applied. The microcomputer 30 controls the winding data section 35
By sequentially reading the contents of the second set of 2 bytes, the third set of 2 bytes, and so on, the windings are formed with the desired winding pitch. Here, since the winding pitch for each turn is individually specified by the data B, by changing the value of the data B, an arbitrary winding distribution can be obtained. For example, by increasing the number of pulses of the feed pitch, a so-called window opening is formed where almost no winding is applied. Furthermore, when data A is expressed in hexadecimal notation, A=
When the value is 16, a ₁ and a ₀ become 10, the motor 31 rotates at high speed, and high-speed winding operation is performed. Furthermore, flyer pulse irrelevant (a ₃ and a ₂ are 00) is used during the return operation described later, and pulse motor stop (a ₅ and a ₄ are 00) is used when starting winding. When the first layer of the core 4 has been wound a predetermined number of times, the microcomputer 30 reads out the next data set. Data A (00100101) = 25 Data B (11111111) = FF By reading this data, the fryer 1 rotates at a low speed, and the computer 30 issues a pulse motor reverse instruction and a 255
A pulse group 45 (shown in FIG. 4C) is applied to the pulse motor 32. As a result, the rotary table 2
is rotated by 25.5 degrees in the opposite direction shown by arrow _B2 in synchronization with the flyer pulse FP, and the core 4 is returned to its original position. Furthermore, in order to return the table 2 to a large angle, the data to be read next is determined as follows. Data A (00100000) = 20 Data B (11111111) = FF By reading this data, the flyer 1 is stopped, and a group of 255 pulses 45a is applied to the pulse motor 32 regardless of the flyer pulse FP.
As a result, the table 2 is further rotated by 25.5 degrees in the opposite direction. This state is indicated by 46 in FIG. By appropriately determining the contents of the data B, the core 4 accurately returns to the original winding start position, and then the second layer winding operation is performed. In addition, at the end of the winding work, data A is
Data with a ₇ set to 1 is read out. When this data is read, the microcomputer 30
determines that all windings have finished, and issues a command to stop the winding device. This causes the winding device to stop operating. Note that a servo motor can be used instead of the pulse motor 32. In this case, a configuration is adopted in which a rotary encoder is directly connected to the servo motor 32 and a number of pulses generated by the rotary encoder according to the rotation angle of the servo motor are applied to the interface 36. Further, in the above embodiment, a deflection device for a television cathode ray tube device is manufactured as a structure for rotating the core 4, which is the object to be wound, but the present invention is not limited to this. As shown in FIG. 5, the present invention can also be applied to a device that linearly feeds the object to be wound to form a solenoid winding. In FIG. 5, the same components as those shown in FIG. 2 are given the same reference numerals. The bobbin 50 is clamped by a clamp member 51. Clamp member 51
is screwed onto a screw shaft 52 fixed to the gear 44, and moves linearly in the direction of arrow D together with the bobbin 50 as the screw shaft 52 rotates. A wire rod 11 is wound by a flyer 1 around a bobbin 50 that is fed linearly, and a solenoid is manufactured. Furthermore, the winding device according to the present invention is not limited to the flyer method shown in the above embodiment, but
It can also be applied to a mandrel method in which the object to be wound is rotated without using a flyer as shown in the figure. In the figure, the same reference numerals are given to the constituent parts having the same function as the constituent parts shown in FIGS. 2 and 5.
The explanation will be omitted. The bobbin 50 is the drive motor 3
Rotationally driven by 1. 53 is a wire supply mechanism, which is screwed onto the screw shaft 52. By driving the pulse motor 32, the wire supply mechanism 53 is provided with an arrow E.
The wire rod 11 that is supplied from the wire rod 11 at this time is wound around the rotating bobbin 50. In addition, in each of the above-mentioned embodiments, the winding work preparation setting can be performed in about 1/20th of the time of the conventional device without requiring any special skills.
Moreover, the winding time required for each coil is reduced to about 2/3 of that of the conventional example. Furthermore, the above embodiment device has the following features:
The structure is also simpler than the conventional example (compared to the conventional example, 240 mechanical parts, including 25 mechanical parts, such as relays, are eliminated), making assembly and adjustment extremely easy, and failures are less likely to occur. As mentioned above, according to the winding device of the present invention,
A winding mechanism, a winding mechanism drive source that drives the winding mechanism, a mechanism that drives a target object to be wound, and a pulse motor that drives the mechanism that drives the target object. , a detection unit that detects the winding operation of the winding mechanism for each winding and issues a signal; At least two or more motors having a function of driving and controlling the pulse motor by generating a group of pulses in proportion to a predetermined feed amount using the signal as a trigger, and controlling forward rotation and reverse rotation of the pulse motor. having a winding data section including data and at least two pieces of data having a function of representing the rotation angle of the pulse motor, and sequentially reading out the contents of the winding data section;
Since the configuration includes a control means for controlling the forward rotation, reverse rotation, and stop of the pulse motor and the rotation angle at which the pulse motor is to be driven depending on the content thereof, it has the following features. The windings on the object to be wound can be formed at any pitch per turn, and thus the windings can be formed with any desired winding distribution. The range in which the wire is formed on the object to be wound can be freely controlled. The number of turns of the wire to be wound on the object to be wound can be freely controlled. Particularly, when forming the core winding of a deflection device of a television cathode ray tube device, the above steps can form a winding such that the magnetic field inside the deflection device has a desired magnetic field distribution. The mechanism for driving the object to be wound is driven using a pulse motor, and the pulse motor is driven and controlled by a group of pulses, so that the object to be wound can be driven (moved) with high precision. Therefore, the winding accuracy can be considerably increased, and variations in the winding can be extremely reduced. There is no need to prepare many types of gears, the mechanism can be greatly simplified, and settings for operation preparation can be made in a short time without requiring special technology. If the winding mechanism is a flyer and the mechanism for driving the object to be wound is a rotary table for rotating the object to be wound, it is suitable for forming the winding around the core of the deflection device. The winding pitch is not limited to a fixed value, and the winding pitch can be changed in the middle, making it possible to perform winding with complicated specifications, and the winding device has excellent operability and mass productivity.
